Components:

(1) 1,3-Dichlorobenzene, C₆H₄C₁₂; [541-73-1] NIST WebBook
(2) Water, H₂O; [7732-18-5] NIST WebBook

Original Measurements

Vesala, A.; Acta Chem. Scand. 1974, 28A(8), 839-845.

Variables:

Ambient temperature: One temperature

Prepared by:

A.L. Horvath

Method/Apparatus/Procedure:

Equilibrium was established between the water and the 1,3-dichlorobenzene in a sealed flask (1) with the aid of a magnetic stirrer during 48 hours under isothermal conditions. After the sample was filtered through a glass-wool plug, the 1,3-dichlorobenzene was extracted with 2,2, 4-trimethylpentene. Sample optical densities were determined spectrophotometrically (2). Five parallel determinations were done. The reported work was based upon a Ph.D. dissertation (3).

Source and Purity of Materials:

1. Commercial reagent of analytical grade distilled through a column resulting in a more than 99% pure sample.
2. Distilled, deionized, and degassed.

Estimated Errors:

Ambient temperature: ±0.05 K.
Mass concentration (m/v) (1): ±1.0%.
